how to list multiple boxes dimensions in one table? (for wood workers)
I'm switching from 3Ds Max to Blender so I can design kitchens and make cutlist. So, this is what i have so far and I'm trying to figure out more about Blender and Python so I can have a complete solution for kitchen making.

Try this code, this code export selected objects (kitchen cabinet parts) and store it's name and dimensions into csv file so you can open in excel or send it to cutlist programs like MaxCut. 

import bpy
#here you need to write where you want to store the file on your system
file = open("/home/monis/Blender/MyFile_02.csv", 'w')
selectedObjects = bpy.context.selected_objects
file.write('Panel name\t hight\t width\t thickness\n')

for obj in selectedObjects:
    dim = obj.dimensions
    file.write(obj.name+'\t'+'{:.3f}\t{:.3f}\t{:.3f}\n'.format(dim.x*100,dim.y*100,dim.z*100))

file.close()
print(obj)
